To all whom it may concern.-

Be it known that I, J Us'rUs A. TRAUT, a citizen of the United States,residing at New Britain, Connecticut, have invented certain to embody myinvention. Fig. 2 is a plan view. Fig. 3 is a section onthe line 3 3,Fig.

' 1. Fig. 4 is a section on the line 4 4., Fig. 1.

Fig. 3 is a face view of the handle or back portion of the try-squareshown in Fig. 1

looking from left to right, the blade of the square being removed.-

1 is the usual blade ofa try-square, which may be graduated inany'desired mannerf The back or handle portion of'the try-square isformed of a single piece of metal and comprises'two side members orchecks 2 2-. (See section Fig. '3.) These checks are spaced apart thethickness of the blade 1.

2 is the face portion of the back. This face affords a broadbearing-surface, and. it

- determines one of the inner sides. or angles being folded back uponthemselves.

of the square.

portion 2 is of double thickness, thesides These sides are then extendedstraight back and parallel to each other to form the cheek mem bersalready referred to. The face 2 is centrally slotted at one end, asindicated at 3,

. may be a plain straight piece of metal, or it may be formed of a rightangled piece of metal, as would appear in Fig. l,ignoring said dottedline, in which event one end of said bladewould act as a filler-piecebetween said Y the saving of metal.

The face 2" and the cheek pieces 2 2 are formed-integrally. As will be"seen by reference to Figs. 1, 2, and 3, the face m to the same, broadly.The particular construction herein disclosed is, however, from thestandpoint of strength, economy,

and simplicity of manufacture unique and of substantial benefit andadvantage. For example, the number of steps necessary to the completeproduction of the device is reduced to the minimum. Only two pieces ofmetal need be handled, the blade constituting one piece, the back theother. The addition of a separate filler-piece involves no dif-.

ficulties or complex operations, since it need I be but a plain piece ofmetal inserted between'the cheeks. The method of attaching the blade tothe back may be any of the well-known methods already. practiced, suchas riveting. I preferably form an elongated opening, as indicated inFigs. 1 and 4., in the cheeks 2 2, as it affordsa convenient fingergripand results also in a saving in weight and What I claim is'v v 1. In atry-square, a blade, a back or handle portion comprising a face. andcheek members, said face and cheek members being formed integrally froma single piece of metal,

the,face being slotted to receive the blade,

the metal at the side edges of said face being folded back uponitself,-and then projected rearwardly to hold the blade and form a gripportion. 4
